V ELOC|PEDE.

SPECIFICATION forming part of Letters Patent No. 611,138, dated September 20, 1898. Application filed September 25, 1897. Serial No. 653,033. (No model.) Patented in England July 20, 1897,1T0. 17,125.

To all whom it may concern:

Be it known that I, GEORGE ALFRED NISBET, a subject of the Queen of Great Britain and Ireland, residing at 5 Knowsley road, Battersea, London, England, have invented certain new and useful Improvements in Velocipedes, (for which I have obtained a patent in England, No. 17,125, dated July 20, 1897;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

This invention relates to velocipedes; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In order that my invention may be more fully understood, I will now proceed to describe same with reference to the accompanying drawings, in Which Figures 1 and 2 are a side View and perspective view, respectively, illustrating the form of the rear portion of the velocipedeframe according to my invention. Fig. 3 is a side elevation of a velocipede combining some of my improvements and fitted with the improved saddle or seating device, while Figs. 4: and 5 show in side elevation and plan the form of the front portion of the frame of the velocipede according to my invention. Fig. 6 is a cross-sectional view of the saddle or seating device drawn to a larger scale, Fig. 7 being a side elevation of the lower portion of the same. Figs. 8 and 9 are plans of portions of the saddle.

According to my invention and as shown in Figs. 1 to 5 of the accompanying drawings the rear portion of the velocipede-frame comprises the approximately horizontal tubes (1 a b b and the side tubes cc (1 d, Figs. 1 to 3, the whole arranged in such a manner as to produce a flat-topped frame for supporting the saddle or seating device e,'Fig. 3, while the front portion of the frame comprises the semicircular forked portion f, with the extend ing arms f, designed to be brazed to the bottom bracket f and a continuation tube f designed to be brazed to the socket of the head of the machine f.

I provide a suitable rectangular box or case h, designed to rest upon and be suitably secured to the Hat top of the velocipede-frame, as shown at'Fig. '3. Within the box hI provide a traveling block h, mounted upon two pairs of wheels 72. 71 The ends of the axle 11 pass through slots 2', formed in the supporting-lugs 1' while between the said axle e' and traveling block h I interpose a laminated springj and coiled or helical spring j, while the wheels or rollers h k are mounted upon rails 7' The traveling block h is traversed by two rods or wires infer the purpose of guiding same, and around which and between the traveling block and one end of the case coiled or helical springs 7.2, Fig. 7, are arranged and which always tend to force the traveling block h back, said traveling block being locked in position by the spring-clip 16 Figs. 6 and 7, the end of which is bent at right angles and passes through the slot or opening it in the side of the box h, where it is forced into close contact with the traveling block h by the spring 10 while in order to release same it is only necessary to press the lower end of the clip, which draws the toothed or serrated edge of same out of contact with the traveling block 71., when the latter can be adjusted to the re quired position and again locked by the clip.

Upon the traveling block h is mounted a vertical tube Z, within which works telescopically a second tube Z,supported upon a spiral spring Z while between a collar Z on the outer tube Z and the lower plate Z of the saddle a second spiral spring Z is arranged.

The saddle proper comprises the lower plate Z and upper plate 1, each of which is furnished with a stifiening-plate m in the form of a cross and between which are arranged five spiral'springs m in the positions shown at Fig. 8, while the top portion of the saddle may be of leather or other suitable material, padded or not, as required.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a velocipede, the combination, with a frame provided with a rectangular case at its upper part, of a longitudinally-movable block inclosed in the said case, rollers supporting the said block in the case,'and a support for a saddle carried bythesaid. block and projecting through the top of the case, substantially as set forth.

- 2. In a velocipede, the combination, with a frame provided with a rectangular case at its upper part, of a longitudinally-movable block for carrying a saddle inclosed in the said case and provided with lugs on its under side, axles mounted in the said lugs and movable vertically therein, springs interposed between the said block and axles, and rollers supporting the said block and carried by the said axles, substantially as set forth.

3. I11 a velocipede, the combination, with a frame provided with a rectangular case at its upper part, of a block provided with travelin g rollers and arranged in the said case, a support for a saddle carried by the said block and projecting through the top of the said case, and means for locking the block, substantially as set forth.

4. In a velocipede, the combination, with a frame provided with a rectangular case at its upper part, of a block provided with traveling rollers and arranged in the said case, guide mechanism permitting the said block to have free movement in a longitudinal direction only, a saddle carried by the said block, and means for locking the block, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE ALFRED NIS BET.
